We are using a DataList with a couple fields inside the ItemTemplate. The one that is giving me trouble is the Hyperlink. The code is below. When the page loads the hyperlink renders like this:

I am using an ObjectDataSource control to call a MapInfo object. This object has two properties:
public IList Visits
public int TotalAvailable
The select method returns an IList but the TotalAvailable property is also populated. I have set the TypeName in the ObjectDataSource to the MapInfo object but because the Select method only returns the IList I don't have access to the TotalAvailable.
[code]....
Is there any way to access this value. I know it is being populated in the MapInfo object but all that gets returned from the Select method is the IList

I have a form where a user enters their name, date etc.i also want them to be able to click on a browse button and select a file which will then appear in a textbox. when they press submit i want the file name and path to be put into the database. e.g."C:windowsworkwork.doc". Basically I don't want to UPLOAD the file
just enable the user to browse to it and send the filename and path to the database.

how to "discover" hyperlink in some text and convert that hyperlink in html hyperlink with asp.net (or javascript). For example, if a user enter this text:
You found it at [URL]
How can i found and convert in html like :
You found it at <a href='http://www.foo.com'>http....</a>
i have a pie chart but i am not able to put a hyperlink on that chart.
i have put an on-click event to navigate to a new page but that also does not work..

Is there anything missing in IIS 6.0 that prevents me from (Insert into table) using MS-Access?
Explain: The application works fine under Visual Studio 2008 IDE the insert into table works fine with no error, Also I tested with hosting provider and works fine with no problem. but now I have published the same exact app in a dedicated server windows 2003 with
IIS 6.0 .NET framework 2.0 with latest service pack I gave IIS_WPG write/modify access to the folder where MS-Access database is located and database but at the time of insert an error pop-up. I need to install in the Server or settings in the IIS to recognize my MS-Access db is it some office runtime that I am missing. (BTW I am using OLEDB connection string in my C# )
Using System.Data.OleDb;
I can retrieve data off of it with no problem but when I try to insert is when it fails I thought the problem was Access Rights but I do not think is the case.
Working on an ASP.NET 4.0 project, which uses user controls to dynamically generate a form based on definitions stored in the database. One form field would look like this:
[code]....
Behind the scenes the control emits a RegularExpressionValidator based on the RefControl.ValidationFormat property.
This works fine, however the problem is that this architecture only allows us to validate with regexes. Now I need to add date format validation, based on the user's preferences (which aren't dependent on their UICulture).
Reluctant to refactor the entire user control setup, I need to be able to pass a on-the-fly regex pattern to the ValidationFormat property. Currently I'm using a data binding expression to bind the property to a page instance method:
[code]....
Works okay on first page load, but on subsequent postbacks the validation doesn't work. I think the issue is that the data binding expression doesn't evaluate at all, but I'm not sure I understand why. I'm calling Page.DataBind() in Page_Init whether Page.IsPostBack or not, so shouldn't this work?
If you see I'm barking up the wrong tree, any alternative solutions to the same problem are also welcome.
EDIT
Managed to solve this problem. The issue was with the way ASP.NET page life cycle invokes the user control's events before the page's own events. The control values were being initialized before the data binding on the page could happen.
Because I still need to do the control initialization before Page_Load to subscribe the controls to viewstate, I simply moved the initialization logic to the Page.InitComplete event so the call to Page.DataBind() could get called first.
protected void Page_Init(object sender, EventArgs e)
{
Page.InitComplete += new EventHandler(Page_InitComplete);
}
So the event tree becomes
User Control Page_Init => Hook InitComplete handler
Page (aspx) Page_Init => Bind data
User Control Page_InitComplete => Initialize the control
In MainPage.aspx I have
<asp:HyperLink runat="server" NavigateUrl='<%#"http://google.pl"%>'>test</asp:HyperLink>
It does not add an href tag but only outputs <a>test</a>.
When I do:
<asp:HyperLink runat="server" NavigateUrl='http://google.pl'>test</asp:HyperLink>
It works fine.
Why <%#"http://google.pl"%> does not work ?
How to debug it ?
I'm databinding a radiobuttonlist with a LINQ query like so:
var query = from m in Db.Udt_Menu
orderby m.Name
select m;
this.radMenuSelection.DataValueField = "menuID";
this.radMenuSelection.DataTextField = "name";
this.radMenuSelection.DataSource = query;
this.radMenuSelection.DataBind();
However, when i want to update the record I need to set the selectedindex of the radiobutton to a value from the database. There is a table called udt_PageMenuSelection which has a column called menuID which is a foreign key to udt_Menu.menuID.
When i want to update an existing record, how do i set the selectedindex of the radiolist to the value equal to udt_PageMenuSelection.menuID ?
Do I need to do an additional query?
basically I had a repeater that i needed to be able to now update row by row. I thought the easiest way would be to replace with a datagrid.
Here is the code:
Code:
[code]....
If I take away the select filtering, I then get this error on rowdatabound
Unable to cast object of type 'System.Data.DataRowView' to type 'System.Data.DataRow'.
I have in my code behind the following property
public string Firstname {get;set;}
when I want to bind it to some textbox I do the following:
<asp:TextBox runat="server" ID="txtFirstname" Text='<%# Bind("Firstname") %>'/>
then I want value put in this textbox to be set in my Firstname property (because I want to process it e.g. save this value) in my presenter.
[code]....
Would a call to a database be called if you put the databind method in the PreRender event of a listbox and the listbox was rendered on the screen for example? This is a specific example regarding a listbox, but basically does code in PreRender only get called if the control is rendered on the screen. If this is so, is it good practice to put code into PreRender such as databinding?

((Alert)Container.DataItem).AlertId.ToString() the value I get for SystemObjectRecordId in debug is null (but it still works when assigned to the text attribute of a literal).
5) The location of the User Control is default.aspx and the control is comments.ascx. The code files do not share a namespace.
6) I have tried manipulating the OnItemDataBound property of my repeater but since I have proven with the literal that data is getting bound using a declarative value I am not sure what else I could be doing inside the method logic of OnItemDataBound.
Once the end-user makes a comment in the UI, the SystemObjectRecordId value (which should have already been assigned when the page loaded - and we know it does in the case of the literal) should get passed to the codebehind of the custom usercontrol:

No matter what I do, I always get zero for SystemObjectRecordId when passed via the custom user control I have on my default.aspx page.

I'm very new to using Linq-to-SQL, that's why I'm asking this question. I've searched the site, but can't seem to figure out how to do this.
My problem is:
I have a database mapped with LINQ to SQL:
Table 1: PersonalTasks
TaskId
Header
[Content]
IsDone
CreatedDate
Table 2: Comments
CommentId
TaskId
UserId
Comment
CreatedDate
I have a repeater:
<asp:Repeater ID="PersonalTaskRepeater" runat="server">
<ItemTemplate>
<%#Eval("Header") %>
<%# Eval("Content") %>
Task done: <asp:CheckBox ID="IsDoneCheckBox" runat="server" Checked='<%#Eval("IsDone") %>' /><img src="Images/tick-circle.png" />
Here i want to access the comment table, with the comments related to the taskID
</ItemTemplate>
</asp:Repeater>
I've tried using: <%#Eval("Comment.Comment1")%> but that throws this error:
DataBinding:
'System.Data.Linq.EntitySet`1[[Assistr.Models.Comment,
Assistr, Version=1.0.0.0,
Culture=neutral,
PublicKeyToken=null]]' does not
contain a property with the name
'Comment'.
My code-behind:
var tasks = db.PersonalTasks.OrderBy(x => x.IsDone).ToList();
PersonalTaskRepeater.DataSource = tasks;
PersonalTaskRepeater.DataBind();
Do I need to use 2 repeaters to do what I want to do or? :)
I'm trying to build a webpage without using any asp.net data binding controls ( listview, repeaters etc.)that I'm trying to do is to use stored procedure to get all necessary items, loop through them, and bind to labels, images etc.The problem is when i want to repeat .aspx code. I'm able to do everything i want in c#, but it's really pain to create all the necessary html elements such breaklines, spans, textboxes and so on.I tried to use expression builders, but it only repeats the last value from database.
Here is my code(ASPX):

I have Wizard steps in a a Wizard control. Each step looks like a form with textboxes and dropdowns for users to complete. I don't want to lose the data as user completes each of the wizard step.
1. I'm thinking about saving user input to sql database when user clicks the next button with each wizard step but I wonder if this is wise since it would create many runs and writes to the server? If not the best way then what method should I use? I just don't want user to lose data if browser crash or for any reason.
2. Or should I use the DataBinding option in the Wizard? Would this be a better performance?
3. Another concern I have is that there are on average about 7, 8 HTML-Server CONTROLS (I added id and Runat="server" to the regular html controls) in a wizard step. If I load up all 7 steps and each step has 8 controls then is that a lot of controls? Wouldn't that affect performance easily when there are a few more users access this web app? Maybe I shouldn't use Wizard for this then? I should just have 7 forms and each form would have Next and Prev buttons that takes users to whatever page they want?
